and lay it fiat on the inner surface of the shoe.

Prior to my invention various devices have been produced for raisingthe'lip and settingit in a predetermined position, one of whichcomprises a reciprocating hammer which is arranged to strike the lip itsbase and upset it, so'that it will beheld n a verticalor slightlybent-over' pos'ition. This method is objectionable for the reason that,asthe blow of the hammeris directed at the base of the lip, itfrequently tears the 11p from the sole or weakens the portion of theleather which connects it to the sole and places an objectionable strainthereon.

In another type of machine more nearly similar to ,the machine whichconstitutedthe subject-matter of my invention, in which the purpose isnot only to raise the lip, but

to bend it back and layit flat on the surface of the sole, a hammer isprovided with means for causing it' tostrike a vertical blow, on

the lip after it has been raised by the plow and bent back to or beyondthe vertical position'. With this type of machine the lip is frequentlystruck. directly on its edge,

while in a vertical position, causing it to be beaten down without beingbent over; This is especially liable to occur when the lip is short andthick.' V

Difficulty has also frequently been encountered in setting the lip inbent-Wei position when it is short and thick, as it tends strongly toreturnto its natural position. 7

The object ofmy invention 1s to provide a machine 0f the above characterwhich is adapted to raise the lip and then turn it over and .down ontothe surface of the sole, so

that it will be set in this position without liability of having thelip-setting means beat down the lip without having it turned over.

furtherobject is to providea machine which shall be of simple anddurable construction, sothat it is unlikely to get out of order, and maybe manufactured at small expense.

I accomplish these objects by the means shown in the accompanyingdrawing, in which, V V Figure 1 is a side elevation of a machine madeaccording to my invention.

Fig. 2 is a plan view thereof, and

Figs; 3 and 4c are detail views illustrating {he manner of turning overand setting the .lP- Figs. 5 and 6 are detail sectional views of thehammer and its holder.

In the drawing 1 indicates the base of the machine having a bracket 2thereon in which the main shaft 3, which is driven from a suitablesource of power, is mounted. Said shaft has aneccentric 4 thereon onwhich a block 5 is mounted, said block being an ranged to slide betweenthe arms of a lever 6 which is mounted to oscillate on a shaft 7 in abracket 2, so that as said shaft 3 is driven said lever will beoscillated.

The shaft 3 is also provided with a worm 9 which isarranged to engage aworm gear 10 mounted on an inclined shaft 11, said shaft being journaledin the base of the machine and also in a bracket 12, secured to thefront side thereof. A feed wheel 13 is mounted on the upper end of saidshaft, said feed wheel being adapted to bear on the edge portion of thesole from which the lip has been out. A vertically yielding shaft 14 ismounted to rotate vertically in the bracket 12, and is provided with acircular feed table 15 on the upper end thereof, and

suitable treadle mechanism, not shown, for drawing down'the table isprovided. A gear 16 is mounted on the shaft 11 and arranged in mesh withthe gear 17 on the shaft 14, so

that the sole-engaging portions of the feed wheel and table are drivenat the same sur-' face speed. I

According to my invention I provide an arm 18 which is mounted on pivot19 ad jacent the base of the machine, at a considerable distance beneaththe level of table ,15, and also some distance in the rear thereof, andextends upwardly from said pivot to points above the level of the table.Said arm 18 is provided with a socket 18 which extends at right anglestherefrom at its upper end, and a depending hammer holder 20 isadjustably mounted in said socket and is adapted to be secured thereinby a clamping screw 21.

A hammer 22, which is square in crosssection, is reciprocally mounted ina correspondingly shaped recess in said holder 20, in a position nearlyparallel to the arm 18 and a screw 220 extends through said holder andis threaded in the upper end of the hammer, the head of said screwnormally resting on the upper end of the holder. A spring finger 23 issecured on the lever 18 and rests on the head of the screw 220 andnormally holds the same against the holder.

The lower end of the hammer 22 is provided with an engaging face 22,which is obliquely inclined with relation thereto, as shown in Figs. 3,i and 5. A link 24 is 0011- nected to the upper end of the arm 6 and tothe upper end of the arm 18, so that as the shaft 3 is rotated, said arm18 will be occillated.

A plow 25 is mounted on brackets at one side of the hammer 22, inposition to pass between the surface of the sole and the lip, so as toraise it in the usual manner.

A lip depressing finger 26 is also rigidly secured onbracket 27 at theopposite side of the hammer 22 and in position to bear on the lip,afterit has been turned over, as hereinafter described.

In operation, the table is rotated in the direction of the arrow in Fig.2, and the sole is passed between the table and the feedwheel 13 in theusual manner.

The arm 18 is oscillated, and, as the center about which it swings islocated at a considerable distance below the level of the table 15, andin the rear thereof, the hammer 22, which is held so that it dependsdirectly over the edge portion of the table in a nearly verticalposition with relation thereto, will be carried laterally, or in adirection transversely thereof, and with its face nearly parallel to thesurface of the table, and, at the same time also longitudinally downwardtoward the table. The path of movement of the hammer is such that itsface 22 either is caused to engage the edge of the lip which haspreviously been raised by the plow, or its front side is caused toengage the side of the lip closely adjacent its edge and to bend it overand press it, or hammer it down, so that it lies flat on the innersurface of the sole, as shown in Figs. 3 and 4-. llhat is, the hammerstrikes down on the lip with what may be termed a drawing blow. The face22 of the hammer is made slightly oblique to the sides thereof, so thatsaid face will be held flat with the sole at the end of its strike, andwill also have a drawing or pushing effect until it reaches that point.As the hammer is adapted to yield upward, slightly, against the actionof the spring 23, and as-the table 15 is also adapted to yielddownwardly, variations in thickness of soles and of the lip are providedfor.

"Whether the hammer first strikes directly on the upturned edge of thelip with its face 22, or whether its side first strikes the under sideof the lip and then pushes it over, so that the lip is then engaged byits face 22, depends on whether the lip is short or long, and on thevertical adjustment of the hammer by screw 220.

While the hammer will press the lip down from the vertical position of Fi 3 to the position of Fig. i, the lip will not always be fully set inthis position, and for this reason I preferably provide the finger 26which bears firmly on the lip after it is turned down, and as the soleis fed beneath it, and materially assists in setting the lip in theturned down position.

While the above described construction is a preferable form of myinvention, various other forms of mechanism may be produced which willcause the combined downward and forward movement of the hammer, abovedescribed to take place.

I claim V 1. A lip-turning machine comprising a sole support, a plow forraising the lip, a hammer having a face at its end, and means to holdsaid hammer with its face approximately parallel to the face of saidsupport and to cause simultaneous transverse and longitudinal movementsthereof, so that its said face is carried over and toward the surface ofthe sole supported thereon, to bend back the lip and beat it down towardthe sole.
